Mathematical
Mathematical expressions include the following functions que reciben una variable que representa un time series.
​
Syntax
Description
​
ceil(x)ceil(x)
​
Returns the rounded integer greater or equal for each element in the variable x. The ceil function always rounds up to the nearest integer.
​
round(x,n)round(x, n)
​
Returns the floating-point value rounded to the n digits after the decimal point for each element in the variable x. By default, n equals 2 in Ubidots.
​
sin(x)sin(x)
​
Returns the sine in radians of each element in the variable x.
​
cos(x)cos(x)
​
Returns the cosine in radians of each element in the variable x.
​
tan(x)tan(x)
​
Returns the tangent of each element in the variable x.
​
arcsin(x)arcsin(x)
​
Returns in radians the inverse sine of each element in the variable x.
​
arccos(x)arccos(x)
​
Returns in radians the inverse sine of each element in the variable x.
​
arctan(x)arctan(x)
​
Returns in radians the inverse tangent of each element in the variable x.
​
arctan2(x,y)arctan2(x, y)
​
Returns in radians the trigonometric inverse tangent using the input variables x and y as Cartesian coordinates. Note: It will only perform the operation between values with the same timestamp.
​
sinh(x)sinh(x)
​
Returns the hyperbolic sine of each element in the variable x.
​
cosh(x)cosh(x)
​
Returns the hyperbolic cosine of each element in the variable x.
​
tanh(x)tanh(x)
​
Returns the hyperbolic tangent of each element in the variable x.
​
arcsinh(x)arcsinh(x)
​
Returns in radians the inverse hyperbolic sine of each element in the variable x.
​
arccosh(x)arccosh(x)
​
Returns in radians the inverse hyperbolic cosine of each element in the variable x.
​
arctanh(x)arctanh(x)
​
Returns in radians the inverse hyperbolic tangent of each element in the variable x.
​
exp(x)exp(x)
​
Returns the exponential of each element in the variable x.
​
log(x,base)log(x, base)
​
Returns the logarithm of each element in the variable x. By default, the base is the Euler's number.
​
abs(x)abs(x)
​
Returns the absolute value of each element in the variable x.
​
sqrt(x)sqrt(x)
​
Returns the square root value of each element in the variable x.
